A Yubel Deck primarily revolves around the use of the 3 'Yubel' monsters, and supporting their evolution to their next level, while preventing your opponent from getting rid of Yubel until you want it to be destroyed, and thus evolve to its next level.

Another big problem is a Lightsworn deck. Judgment Dragon can cause serious problems by paying out 1000 LP's multiple times to get rid of all 3 Yubels and attack for Game. Side decking some Light-Imprisoning Mirrors will help and possibly a Soul Release to counter act the mighty Judgment Dragon.Another good way to counter a Lightsworn deck would be Karma Cut, as it would remove a monster from play and all multiple copies of it in the graveyard, thus stalling the summon of Judgment Dragon.

By adjusting the Doom Shaman/Swing of Memories Yubel Deck, it becomes possible to integrate the Fusilier Dragon, the Dual-Mode Beast / Deck Devastation Virus / Eradicator Epidemic Virus group of cards, and by utilizing the ease with which Yubel-Terror Incarnate can be summoned as a stalling strategy until Doom Shaman or another appropriate monster can be summoned for Deck Devastation Virus Fodder, Fusilier Dragon is drawn into for Eradicator Epidemic Virus, or, waiting until an opponent overextends to destroy Yubel-Terror Incarnate and Yubel-The Ultimate Nightmare to play Crush Card Virus and severely punish them for the play. The primary issue is being able to capitalize. There are a couple of answers to that, and thats what the rest of the deck is made up of.
